Abstract

The invention relates to a method for producing a bearing body for the female connectors of a bed frame, which consists of receiving caps for the ends of the female connectors and fasteners interacting with shaped brackets. According to the method, the bearing body (1), consisting of a thermoplastic elastomer, and the brackets (4), which consist of a polymeric material, are manufactured in an injection molding tool.

Description

  • The invention relates to a method for producing a Bearing body for the female connectors of a bed frame, which consists of receiving caps for the ends of the female connectors, as well as with shaped brackets interacting fasteners.
  • From the state of the art according to utility model G 94 07 423.2 storage for wooden slats on the base frame of a slatted frame known. The bearing body itself consists of a spring element, are integrally formed on the receiving caps into which the ends of the Female connectors are inserted and stored. The bearing body itself below the receiving caps over molded eyelets, into each a mounting element designed as a dowel is inserted. In the Production of such a bearing body according to the known State of the art, the bearing body on the one hand and the Dowel-shaped brackets on the other hand, due to the Driving into holes on the slatted frame made of a harder material are manufactured, manufactured separately. To ensure security against rotation or Restoring force of the receiving caps on the bearing body ensure that the dowel has cross-sectional shape on its Shaft area. For the production of a seat that fits exactly or fits perfectly of the dowel shaft in the eyelets of the bearing body is first the Bracket designed dowels on a separate Injection molding device made, then the cured dowel by hand in a separate injection molding device is used to then on this to form the bearing body, then the eyelet-like holder around the prefabricated dowel is injected.
  • As a disadvantage in such a method for producing a Bearing body, it is considered that the process is complex represents, since a separate production of the parts is required, which only with manual use or with the interposition of a Robot is feasible. The prefabricated dowels must be in a injection molding unit to be manufactured for the bearing body become, which results in cost-intensive production.
  • It is therefore the object of the invention before the shown state of the Technique a method of manufacturing a bearing body for the To provide female connectors of a bed frame, which of the Cost side is much cheaper.
  • This object is achieved in that the Bearing body consisting of a thermoplastic elastomer, as well as the Brackets, which consist of a polymeric material, in one Injection molding tool are manufactured. Because of this training achieved that in one operation from two plastic components existing bearing body with a thermoplastic elastomer as well a polymeric material is manufactured in an injection mold. For this purpose, it is proposed according to the method that in a first Process step the mounts designed as dowels in one chamber of the tool initially closed by a slide be injected and after pressing the slide in one second process step of the bearing body in the form is introduced that the polymeric material of the anchor with the elastomer of the bearing body enters into a welded bond. This Procedure ensures in particular that the form is not yet completely solidified dowels as a result of the inserted into the injection mold different components in the transition area, so here the areas between the bracket and the bearing body, enter into a chemically welding connection. This welding connection in particular brings about the required restoring effect the female connector opposite the fixed dowel on the elastomer trained receiving cap of the bearing body.
  • According to the invention, a bearing body for the female connectors Bed frame is provided, which consists of receiving caps for the ends of the Female connectors as well as interacting with shaped brackets Fasteners consists, which has brackets made of polymeric materials and are made directly from the existing thermoplastic elastomer bearing body are molded. Thereby there is a chemical compound that results from a physical Support is worn in addition. Because by the fact that the Shaped webs in the caps designed as dowels Grips are form-locked. This surrounds after a first embodiment of the web, the dowel sleeve-like, wherein According to a further embodiment, the web by a dowel molded slot engages. According to a further embodiment, it intervenes the bridge into a groove formed on the dowel.
  • An embodiment of the invention is explained in more detail with reference to FIGS. 1 to 7 below:
  • Fig. 1 is a perspective view in a bottom view of a bearing body:
  • Figure 2 is a perspective view of a holder designed as a plug in a first embodiment.
  • FIG. 3 shows a further embodiment of a holder according to FIG. 2;
  • Figure 4 is a perspective bottom view of the bearing body with molded brackets.
  • FIG. 5 shows a further embodiment according to FIG. 4;
  • Fig. 6 is a rear view of a bearing body and a further embodiment;
  • Fig. 7 is a side view of a bearing body according to FIG. 6.
  • Fig. 1 shows a perspective view of a bearing body 1 for not shown spring strips of a bed frame. The bearing body 1 has receiving caps 2 and 3 for the ends of female connectors. In FIGS. 2 and 3 differently shaped holders 4 are shown, which together act as fastening elements on a bed frame with the bearing body 1. As can be seen from the combination of FIGS. 1, 2 and 3, the production of the bearing body 1 is effected by the inventive method in that the bearing body 1 is formed from a thermoplastic elastomer, and the holders 4, the polymer of a Material exist, are manufactured in an injection molding tool, not shown.
  • In a first process step, the holders 4 designed as dowels 5 are first injected into a chamber of the tool closed by a slide, and after actuation of the slide in a second process step the bearing body 1 , as shown in FIG. 1, is introduced into the mold in such a way that the polymeric material of the dowel 5 forms a welding connection with the elastomer of the bearing body 1 .
  • How the bearing body 1 appears in the finished state can be seen in particular in the perspective views of FIGS. 4 and 5, where it can be clearly seen how the bearing body 1 formed in an injection molding tool results. It is also clear from FIGS. 2 and 3 that the slide, not shown, in particular omits the groove 6 provided on the dowel 5 according to FIG. 3 or the slot 7 according to FIG. 2, so that the molded on the bearing body 1 Crosspieces 8 and 9 can be injected into these areas of the dowel 5 . In these areas in particular, the bearing body 1 enters into a welded connection with the dowel 5 . This means that an inseparable connection is created, particularly in the border areas of polymeric material and thermoplastic elastomer, so that bearing body 1 and dowel 5 become a molded body.
  • FIGS. 6 and 7 show a third variant of the bearing body 1, in which case the dowel 5 is first injected into its full shape and initially covered by an annular or sleeve-shaped slide. If the annular slide is removed, sleeve-shaped eyelets 10 and 11 , which consist of thermoplastic elastomer, can be sprayed on around the prefabricated dowel 5 . Because of this arrangement and process steps, it has become possible in the context of a two-component injection molding process to produce a bearing body 1 which is inexpensive and which provides the sufficient supporting force for the female connectors.
